Hello all, I wanted to post some progress on this, so I am going to do a photo essay. My usual video will appear very soon. So for this build, I am going to mix photos and video!
The first thing I did was spend some time looking for reference material. Here are a few good links, the first one is outstanding:

Jamaicanmodels69 provided this link, I have only glanced at it, but it looks promising!

The next one got me started on a long internal debate, more on this later:

The A-wing photos are further down on the page.
What got me started was the photos of the rear of the studio model provided by Lucasfilms:
The engines appear to be warm white in color. But most of the model builds I have seen are amber. So I spent quite a bit of time trying to resolve this on the net. Comments are welcome! Let me know what you all think about this. Amber or Warm White. I am also going to post that question on the YouTube video when it comes up.
Up first is the snap kit:
The first photo shows one of the engine cans:
She is just cleaned up and ready to be put together.
The next photo shows the rear of the engine cans. I am going to light her up, and the video will detail that out much better later this week. The LED's are 3mm and I drilled out 9/64 inch holes for the LED's. That is about 2.98 MM. Which fit the LED's perfectly as shown here:

The LED's for the snap kit are amber. I didn't have any 3mm warm whites on hand, and I don't want to delay this build any longer. So I went ahead and used amber LED's. I have an order coming in from China soon, so I will have warm whites, but not in time for this build.
The reason is that I am using the snap kit as a guide for the larger version. I want the engine cans done on the snap kit, then I can work on the larger version.
